Demographic and psychological moderators of the relationship between neighborhood cigarette advertising and current smoking in New York City

Background: Tobacco advertising in retailers influences smoking, but little research has examined how this relationship differs among population subgroups. This study merged data on neighborhood cigarette advertising with geocoded survey data to assess the association between advertising prevalence and current smoking among New York City (NYC) residents, and whether demographic and psychological characteristics moderate this relationship. Methods: Audit data from a stratified, random sample of 796 NYC tobacco retailers generated neighborhood prevalence estimates of cigarette advertising, which were linked with unweighted 2017 NYC Community Health Survey data (n = 7837 adult respondents with residential geocodes). Multilevel regression estimated adjusted odds ratios (aOR) of current smoking by level of neighborhood cigarette advertising (quartiles). Interactions assessed differences in this relationship by demographic characteristics and current depression (analyses conducted in 2019). Results: There was no main effect of advertising on smoking status or significant interactions with demographic variables, but current depression was an effect modifier (p = 0.045). Cigarette advertising was associated with current smoking among those with current depression (p = 0.023), not those without (p = 0.920). Specifically, respondents with depression who resided in neighborhoods in the highest quartile for cigarette advertising prevalence had higher odds of current smoking, compared to those living in the lowest advertising quartile [aOR: 1.72 (1.04, 2.86)]. Conclusion: Retail cigarette advertising may serve as an environmental cue to smoke among adults with depression. Efforts to restrict or counteract this practice, such as the development of community-level public health interventions and counter-marketing programs, may particularly benefit those with depression and, perhaps, other mental health disorders.
